BBC Wales makes television programmes in both the English and Welsh languages. It is the largest BBC production centre outside London. Some of what the channel has produced has been for consumption throughout the whole of the UK, but much of it is only broadcast within Wales.

This heavy output of material related to the Whoniverse prompted the largest expansion of production facilities in the division's history. In 2006, BBC Wales leased a site at Upper Boat in Pontypridd, where they constructed studio space entirely dedicated to the production of Doctor Who and its spin-offs. Called simply "BBC Studios", the site is ten times as large as the rest of BBC Wales' studio space in Cardiff and the largest studio complex in Wales. In 2012, BBC Wales' studio space moved to Roath Lock, in the Cardiff Bay area.

Despite the centrality of Doctor Who to BBC Wales' production output, the division has turned out a wide body of other work, mostly for consumption in Wales itself. As of 2016[update], its Welsh language soap opera, Pobol y Cwm, had been on the air for 42 years. Its longest-running English language drama, Belonging — co-starring Eve Myles for a time — lasted ten series.
